SOLE-EDGE PLANE.

SPECIFICATION forming To all whom it may concern:

Be it known that I, WILLIAM F. BULLOCK, of Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Shoe-Makers Edge- Planes; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which-- 10 Figures 1 and 2 are opposite side views, and

Fig.3 an edge view, of an edge-plane of my improved kind.

The nature of my invention is defined in the claim hereinafter presented.

In the drawings, A represents the planestock, it being provided with a tang orshank, B, for fixing it to the handle.

0 is the cutter, which is secured to stock by clamp-screws a a, going through slots 1) b,

made in the stock, such screws being screwed into the shank c of the cutter, and such shank being arranged against one side of the stock. Each of the slots is widerthan its screw-shank, and there is arranged upon each screw a washer,

d, for the head of the-screw to bear against.

The guard is shown at D as clamped to the stock by a screw,c,whose shank goes through the guard and screws into the stock. The hole in the guard forthe reception ofthe screwshank should havea diameter longerthan that of the said shank, in order to admit of the necessary lateral movements of the guard relatively to the shank and cutter. Furthermore, the guard has in its shank two transverse 5 grooves, f, to receive two corresponding tongues, g, projecting from the stock and parallel to each other. These grooves and tongues maintain the guard atits proper altitude with respect to the stock, and guide it while being 0 adjusted or moved laterally.

Both the guard and the cutter are channeled in the usual manner at their upper parts or edges. The objectof having the guard adjustable laterally is to enable the channels of 5 the guard and the cutter to be brought into correct relations to each other after a sharpening of the cutter or wear of either the cutter or the guard.

While the cutter is rendered adjustable toward and from the guard, both horizontally part of Letters Patent No. 253,180, dated February '7, 1862, Application filed hl'ovember 21, 1881. (No model) and vertically, the guard can be adjusted laterally, as set forth.

Now, I do not claim a shoe-makers edgeplane having its stock and guard in one piece, nor one having its cutter and stock in one piece and provided with a guard having no means of adjustin git laterally relatively to the cutter; nor do I claim a welt-trimmer provided with an adjustable guard and collar, as shown and described in the United States Patent No. 157,678, which differs materially from my improved edge-plane, which is for a different purpose, and is channeled in its outter and guard, which is not the case in the welt trimmer or cutter. My invention is to effect in the edge-plane the proper relations of the channels of the cutter and guard, which is to accomplish aresult not required in the Welttrimmer, because it has no such channels and their side lips, and it is to cut from a strip of leather a strip triangular in transverse section 5 whereas the edge-plane is fora difi'erent purpose entirely. In order for it to properly operate, not only must the bottoms ot'the channels of its cutter and guard be in the same curve, but the lips of the channel of the cutter must be in correct alignment with those of the channel of the guard. To accomplish this, not only must the guard be laterally adjustable to the cutter, but the cutter must be vertically adjust-able to the guard. Furthermore, the cutter must be horizontally, orthereabout, adjustable relatively to the guard, as the thickness of the shaving to be removed by the cutter may require, all of which can be accomplished in rnyimproved edge-plane.

I claim as my improvement in the edgeplane as follows, viz:

The combination of the channeled cutter G and its set-screws a a with the stock A, havo WILLIAM F. BULLOCK. Witnesses:
